still in continuity with the axis. 1n the specimen in question the sporo- 
phylls were rather small (only 3-4 cm. long), whereas they are usually about 
6 em. in length and may even attain to 9 em. Several cones with larger 
sporophylls still attached are figured here from Dr. Moysey’s collection from 
the Middle Coal Measures of Derbyshire. In each ease the laminas of 
the sporophylls are narrowly lanceolate, not more than 3 mm. broad, and the 
apex is markedly acuminate. These seem to be the chief characters of the 
species. 
No. 4014. On PI. 8. fig. 11 a cone is seen, natural size, showing the 
external surfaces of markedly acuminate sporophylls. Below the cone is 
broken across radially and shows two sporangia on each side of the axis. 
The length of the lamina of the sporophyll is 7°3 em. and that of the pedicel 
exceeds 7 mm. 
No. 4015. Another cone, also fractured obliquely below, is figured natural 
size on Pl. 8. fig. 12. Here the laimina exceeds 4 em. in length and the 
pedicel is at least 8 mm. long. 
No. 4016. A further cone witi sporophylls attached is seen on Pl. 8. 
fig. 13. The sporophylls are here very clearly seen. They are between 
4-5 em. in length and the greatest breadth is about 5 mm.
